Jeans will vibrate when it’s time to turn

French startup Spinali Design has created jeans that will vibrate on your right or left hip to let you know which direction you should head. A chip embedded into the waist is connected to an app. Just enter your destination ahead of time.

Of course, a smartwatch can do that, too, but why get something that can do more? The technological capabilities of the jeans are limited to directions.

However, the company also has bikinis that will buzz when you’re out in the sun too long and need to apply more sunscreen lotion. You enter information on your skin type and SPF level of your sunscreen into an app. The chip then monitors the sun rays.

Spinali says the chip should last four years even with constant use and will turn off automatically when wet to avoid damage.
